and to his description adds a few re marks relative to its habits and furnishes also an account of another insect by which the fly is often destroyed without going into a minute and tedious technical description the following account is of fered as probably sufficient to enable an observer to identify the insect in its vari ous transformations : the hessian fly is a two-winged insect with head eyes and thorax black ; the head is small and de pressed ; the palpi or mouth feelers are three or four jointed â€” the basal one being thc smallest ; the antenna are about half as long as the body and consist each of from 1 1 to 17 oval joints besides the ba sal joint which appears double ; the wings arc large hairy rounded at the tip and have each two or three longitudinal nerv ures ; the abdomen is of a tawny red and furnished irregularly with many black hairs ; consists of seven rings or segments besides the ovipositor which is of two sides and of a rose-red color ; the ovipos itor when extended to the utmost is about one-third as long as the abdomen : length of body from the front of lhe head to the end of the abdomen about one-eight of an inch ; the legs arc long and slender pale red and covered sparsely with dark hair the male is equal in size to the female but generally less black wilh an tenna somewhat longer and about three fourths the length of ihe body the joints of the antenna are globular and slightly separated from each other several other species of the genus cecidomyia or one closely allied to it arc common in ibis re gion but the hessian fly is the largest and darkest of our species with which i am acquainted the eggs are laid in the long creases or furrows of the upper surface of the leaves (/. e the blade or strap-shaped pari oflhe young wheat plant while depositing her eggs the insect stands with her head to wards the point or extremity of the leaf and at various distances between the point and where the leaf joins and surrounds the stalk the number found on a single leaf varies from a single cg-z up to thirty or even more the egg is about a fiftieth of an inch long cylindrical rounded at the ends glossy and translucent of a pale red color becoming in a few hours irregu larly spotted with deeper red between its exclusion and its hatching these red spots are continually changing in number si/.e and position : and sometimes nearly all disappear a little while before hatch ing two lateral rows of opaque white spots about ten in number can be seen in each c^jz in four days more or less according lo the weather the egg is hatch ed ; the little wrinkled maggot or larva creeps out of the delicate membranous v skin crawls down the leaf enters the sheath and proceeds along the stalk usu ally as far as thc next joint below here it fastens lengthwise and head down wards to the tender stalk and lives upon the sap it does not gnaw thc stalk nor docs it enter the central cavity thereof but as the larva increases in size it grad ually becomes imbedded in the substance of the stalk after taking its station the larva moves no more gradually loses its reddish color and wrinkled appearance becomes plump and torpid is at first semi translucent and then more and more clouded wilh internal white spots ; and when near maturity the middle oflhe in testinal parts is of a greenish color in five or six weeks varying with the sea son the larva begins to turn brown and soon becomes of a bright chestnut color in this state the insect bears some resem blance to a flax seed : and many observers speak of this as the flax-seal state the larva has now become a chrysalis or pu pa and takes no more food the pupa within gradually cleaves oil from the out er skin and in the course of two or three i weeks is entirely detached from it so that the skin of the larva now brown and har dened and of a sort of lcalhcrly texture has become a case or shell for thc pupa inside the pupa shell is of course in size and form like thc larva : it is oval bulging out beneath and of the same curve above as thc outside of the stalk ; divided by cress lines inlo twelve segments and is about an eighth of an inch long within this shell the pupa gradually advances towards the winged state ; it contracts in length but not in breadth ; and its skin appears covered with minute elevations just be fore evolution we find lhc pupa invested in a delicate membrane or scarf which not long previous was its outer skin through which many parts of the future fly may be distinctly seen finally this scarf splits along the thorax or back and the insect comes forth both from this and and the pupa shell a perfect two-winged fly this is iu brief the history of an indi vidual which has been so fortunate as to escape all the numerous enemies with which its race is surrounded from the mo ment the egg is deposited ; but of these more hereafter in the northern and middle states at ' least winter wdieat is sown in september ! or october soon after the plants have j appeared above ground the hessian fly ! begins to lay her eggs upon them ; and this operation is continued during several weeks according to the season the eggs laid on the green leaves are in a few days \ hatched and the young larva crawl down ! thc stalk and take their stations ; gene ' rally clustering around the stalk at the j | nearest joint below here by sucking of ; the plant they increase in size become ! full and hard and pressing deeply into the ; j stalk they impair its growth ; and if their i number about one joint is large the stalk is killed frequently the plant although ; impoverished advances far enough to head t j out ; but when the grain begins to fill its own weight or perhaps the wind causes the stalk to break down the injury done '< to the wheat is occasioned by the exhaus ; ; tion of thc sap aud by the pressure on the j yielding stalk in five or six weeks the larves stop feed ' ing the outer skin turns brown and with in this brown and leathery case the pupa pass the winter â€” generally a little below the surface of the earth iu april and may the fly is again found depositing her , eggs on lhc same wheat viz : that from ! ' grain sown the preceding autumn and also on thc spring wheat whicli has just come up these eggs hatch and the lar va therefrom operate in thc same manner as those of the autumn previous these j larva become pupa about the middle of june the hies which lay their eggs in ' the spring are probably in part from thc pupa which became such late in the pre ceding autumn and partly from pupae con : tained in stubble left the preceding sum mer thc period of the existence of the hessian fly in the pupa or flax-seed state is exceedingly variable after much ob servation my own opinion is that in gene ' ral pupa which become such late in the autumn evolve the winged insect partly during lhc next spring aud partly in thc summer and autumn following those pupa whicli become such about june evolve the winged insect partly during thc next autumn and partly during the year succeeding the hessian fly is attacked by nume rous foes which in various stages of its existence destroy a large part of every generation whether it has in its winged state any enemies except the ordinary destroyers of flies i know not the eggs while lying on the leaves of thc young plant arc visited by a very minute four winged insect a species of platygaster which lays in them its own eggs from later observation it appears that occa sionally as many as five or six eggs of this parasite are laid in a single egg of the hessian fly the latter egg hatches and becomes a pupa as usual : but from thc pupa case instead of the hessian fly is sues one or more of these minute parasites the pupa while imbedded in lhe stalk are attacked by at least three different mi nute parasites four-winged hymenoptera which boring through the sheath of the stalk deposite their eggs in the body with in ; and the latter is finally devoured by the parasite larvae these are the princi pal means by whicli the multiplication of lhe hessian fly is restrained within tolera ble limits although the loss annually sustained by i the wheat growers of this country in con ! sequence of thc ravages of the hessian fly is severe yet it is well nigh impossible to ascertain even its probable amount as long since as 1800 dr s l mitchill of new york affirmed that the insect i.s more formidable to us than w'ould be an army of twenty thousand hessians in 1804 president dwight of yale college remarked that " this insect is feeble and helpless in the extreme defenceless against the least enemy and crushed by the most delicate touch ; yet for many years it has taxed this country annually more per haps than a million of dollars at the present day the amount of the injury in flicted probably far exceeds what it was forty years stnee ; and to discover some feasible mode of exterminating the insect or at least of arresting its ravages is an object of great importance to this country various remedial measures have from time to time been proposed ; most of j which i will here state 1st steeping the seed-wheat in elder juice solution of nitre boiling water or other liquids ; or rolling in lime ashes or some other substance in order to kill the eggs â€” but as the eggs ofthe hessian fly are not on the seed they will never be hurt by such processes so far as these means give vigor to the plant they may be of some little service 2d sowing seed obtained from places in which the insect has not made its ap | pearance american museum iv 47 â€” this recommendation also assumes the error that thc eggs are laid on the grain and will be found as it has often proved useless as respects this insect 3d abstaining rigidly throughout the ! whole grain-growing region of north a merica from planting wheat rye barley or oats for one two or three years and thus to starve out the insect ! â€” this plan might be effectual but would obviously involve some inconveniences 4th manuring the land very highly so that the plants will grow vigorously and be sooner out of the way of the insect and , also better able to resist it â€” this propo j sal has some merit but docs nothing to : wards destroying the insect 5th sowing some variety of bearded wheat flint wheat c supposed to have a harder and more solid stalk than com ! mon wheat and better able to withstand the impression of the larvae â€” a sugges tion of some value but equally with 4th leaves the insect unharmed cth fumigating the wheat field and sprinkling the young wheat with infusion of elder and with other steeps â€” if success ful which is quite uncertain it is plain that these measures are impracticable on a large scale 7th sowing winter wheat very late in the autumn so that the fly shall have mostly disappeared before the plants arc large enough to be attacked no doubt this plan is lo some extent useful but the wheat sown late is in great danger of per ishing during the winter the fly will of course attack it in the spring yet one at tack will do less danger than two 8th sowing oats early in autumn on the intended wheat-field â€” it is supposed the fly will lay its eggs on the plant ; then let them be ploughed in and the wheat sown thc fly having nearly exhausted itself on the oats the wheat will suffer less this plan may possibly be of some partial utility 9th drawing a heavy roller over the young wheat both in autumn and spring this process must be useful in crushing many eggs and larvae 10 permitting sheep and other animals to graze the wheat-fields while the insects are laying their eggs â€” by these means large numbers of the eggs will be devour ed with the leaves 11th burning the stubble immediately after harvest and ploughing in thc re mains â€” this is by far thc most practica ble and effectual mode of exterminating thc insect or at least of checking its in crease in the stubble are many pupa of the fly at this time completely in our pow er if in reaping thc stubble is left high the fire would sweep rapidly over a field and destroy nearly all these pupa ; the few which escaped the fire would by the plough be buried so deep as to perish in the earth ; mere ploughing in ofthe stub ble must be highly useful if the two re commendations last named were thorough ly put in practice over the whole country â€” not only upou wheat but also on rye and barley and any other plants attacked by the hessian fly â€” the ravages of this in sect would in all probability ere long be come scarcely worthy of notice it may not be improper in this place to state that the foregoing account of lhe ha bits ofthe hessian fly i.s derived irom my own long-continued observations and that i have moreover endeavored to consult all the papers of any importance which have been published on the subject there arc in thc united states besides the hessian fly,several other insects which attack the wheat while in the field those persons who assert that the former lays its cgzs on the grain in the spike or head have undoubtedly mistaken for the hes sian fly some one of these other insects the following brief notices of the more important of these enemies 1 have abridg ed from the accounts comprised in dr t w.harris's " treatise on some ofthe lu st cts of new england which arc injurious to vegetation ;" camb lspj 159 pages 8vo a work of great interest and value in it the inquirer will find a faithful di gest of all the reliable information we have on thc numerous insects which in jure our plants fruits and trees ;

the little wrinkled maggot or larva creeps out of the delicate membranous v skin crawls down the leaf enters the sheath and proceeds along the stalk usu ally as far as thc next joint below here it fastens lengthwise and head down wards to the tender stalk and lives upon the sap it does not gnaw thc stalk nor docs it enter the central cavity thereof but as the larva increases in size it grad ually becomes imbedded in the substance of the stalk after taking its station the larva moves no more gradually loses its reddish color and wrinkled appearance becomes plump and torpid is at first semi translucent and then more and more clouded wilh internal white spots ; and when near maturity the middle oflhe in testinal parts is of a greenish color in five or six weeks varying with the sea son the larva begins to turn brown and soon becomes of a bright chestnut color in this state the insect bears some resem blance to a flax seed : and many observers speak of this as the flax-seal state the larva has now become a chrysalis or pu pa and takes no more food the pupa within gradually cleaves oil from the out er skin and in the course of two or three i weeks is entirely detached from it so that the skin of the larva now brown and har dened and of a sort of lcalhcrly texture has become a case or shell for thc pupa inside the pupa shell is of course in size and form like thc larva : it is oval bulging out beneath and of the same curve above as thc outside of the stalk ; divided by cress lines inlo twelve segments and is about an eighth of an inch long within this shell the pupa gradually advances towards the winged state ; it contracts in length but not in breadth ; and its skin appears covered with minute elevations just be fore evolution we find lhc pupa invested in a delicate membrane or scarf which not long previous was its outer skin through which many parts of the future fly may be distinctly seen finally this scarf splits along the thorax or back and the insect comes forth both from this and and the pupa shell a perfect two-winged fly this is iu brief the history of an indi vidual which has been so fortunate as to escape all the numerous enemies with which its race is surrounded from the mo ment the egg is deposited ; but of these more hereafter in the northern and middle states at ' least winter wdieat is sown in september ! or october soon after the plants have j appeared above ground the hessian fly ! begins to lay her eggs upon them ; and this operation is continued during several weeks according to the season the eggs laid on the green leaves are in a few days \ hatched and the young larva crawl down ! thc stalk and take their stations ; gene ' rally clustering around the stalk at the j | nearest joint below here by sucking of ; the plant they increase in size become ! full and hard and pressing deeply into the ; j stalk they impair its growth ; and if their i number about one joint is large the stalk is killed frequently the plant although ; impoverished advances far enough to head t j out ; but when the grain begins to fill its own weight or perhaps the wind causes the stalk to break down the injury done '< to the wheat is occasioned by the exhaus ; ; tion of thc sap aud by the pressure on the j yielding stalk in five or six weeks the larves stop feed ' ing the outer skin turns brown and with in this brown and leathery case the pupa pass the winter â€” generally a little below the surface of the earth iu april and may the fly is again found depositing her , eggs on lhc same wheat viz : that from ! ' grain sown the preceding autumn and also on thc spring wheat whicli has just come up these eggs hatch and the lar va therefrom operate in thc same manner as those of the autumn previous these j larva become pupa about the middle of june the hies which lay their eggs in ' the spring are probably in part from thc pupa which became such late in the pre ceding autumn and partly from pupae con : tained in stubble left the preceding sum mer thc period of the existence of the hessian fly in the pupa or flax-seed state is exceedingly variable after much ob servation my own opinion is that in gene ' ral pupa which become such late in the autumn evolve the winged insect partly during lhc next spring aud partly in thc summer and autumn following those pupa whicli become such about june evolve the winged insect partly during thc next autumn and partly during the year succeeding the hessian fly is attacked by nume rous foes which in various stages of its existence destroy a large part of every generation whether it has in its winged state any enemies except the ordinary destroyers of flies i know not the eggs while lying on the leaves of thc young plant arc visited by a very minute four winged insect a species of platygaster which lays in them its own eggs from later observation it appears that occa sionally as many as five or six eggs of this parasite are laid in a single egg of the hessian fly the latter egg hatches and becomes a pupa as usual : but from thc pupa case instead of the hessian fly is sues one or more of these minute parasites the pupa while imbedded in lhe stalk are attacked by at least three different mi nute parasites four-winged hymenoptera which boring through the sheath of the stalk deposite their eggs in the body with in ; and the latter is finally devoured by the parasite larvae these are the princi pal means by whicli the multiplication of lhe hessian fly is restrained within tolera ble limits although the loss annually sustained by i the wheat growers of this country in con ! sequence of thc ravages of the hessian fly is severe yet it is well nigh impossible to ascertain even its probable amount as long since as 1800 dr s l mitchill of new york affirmed that the insect i.s more formidable to us than w'ould be an army of twenty thousand hessians in 1804 president dwight of yale college remarked that " this insect is feeble and helpless in the extreme defenceless against the least enemy and crushed by the most delicate touch ; yet for many years it has taxed this country annually more per haps than a million of dollars at the present day the amount of the injury in flicted probably far exceeds what it was forty years stnee ; and to discover some feasible mode of exterminating the insect or at least of arresting its ravages is an object of great importance to this country various remedial measures have from time to time been proposed ; most of j which i will here state 1st steeping the seed-wheat in elder juice solution of nitre boiling water or other liquids ; or rolling in lime ashes or some other substance in order to kill the eggs â€” but as the eggs ofthe hessian fly are not on the seed they will never be hurt by such processes so far as these means give vigor to the plant they may be of some little service 2d sowing seed obtained from places in which the insect has not made its ap | pearance american museum iv 47 â€” this recommendation also assumes the error that thc eggs are laid on the grain and will be found as it has often proved useless as respects this insect 3d abstaining rigidly throughout the ! whole grain-growing region of north a merica from planting wheat rye barley or oats for one two or three years and thus to starve out the insect ! â€” this plan might be effectual but would obviously involve some inconveniences 4th manuring the land very highly so that the plants will grow vigorously and be sooner out of the way of the insect and , also better able to resist it â€” this propo j sal has some merit but docs nothing to : wards destroying the insect 5th sowing some variety of bearded wheat flint wheat c supposed to have a harder and more solid stalk than com ! mon wheat and better able to withstand the impression of the larvae â€” a sugges tion of some value but equally with 4th leaves the insect unharmed cth fumigating the wheat field and sprinkling the young wheat with infusion of elder and with other steeps â€” if success ful which is quite uncertain it is plain that these measures are impracticable on a large scale 7th sowing winter wheat very late in the autumn so that the fly shall have mostly disappeared before the plants arc large enough to be attacked no doubt this plan is lo some extent useful but the wheat sown late is in great danger of per ishing during the winter the fly will of course attack it in the spring yet one at tack will do less danger than two 8th sowing oats early in autumn on the intended wheat-field â€” it is supposed the fly will lay its eggs on the plant ; then let them be ploughed in and the wheat sown thc fly having nearly exhausted itself on the oats the wheat will suffer less this plan may possibly be of some partial utility 9th drawing a heavy roller over the young wheat both in autumn and spring this process must be useful in crushing many eggs and larvae 10 permitting sheep and other animals to graze the wheat-fields while the insects are laying their eggs â€” by these means large numbers of the eggs will be devour ed with the leaves 11th burning the stubble immediately after harvest and ploughing in thc re mains â€” this is by far thc most practica ble and effectual mode of exterminating thc insect or at least of checking its in crease in the stubble are many pupa of the fly at this time completely in our pow er if in reaping thc stubble is left high the fire would sweep rapidly over a field and destroy nearly all these pupa ; the few which escaped the fire would by the plough be buried so deep as to perish in the earth ; mere ploughing in ofthe stub ble must be highly useful if the two re commendations last named were thorough ly put in practice over the whole country â€” not only upou wheat but also on rye and barley and any other plants attacked by the hessian fly â€” the ravages of this in sect would in all probability ere long be come scarcely worthy of notice it may not be improper in this place to state that the foregoing account of lhe ha bits ofthe hessian fly i.s derived irom my own long-continued observations and that i have moreover endeavored to consult all the papers of any importance which have been published on the subject there arc in thc united states besides the hessian fly,several other insects which attack the wheat while in the field those persons who assert that the former lays its cgzs on the grain in the spike or head have undoubtedly mistaken for the hes sian fly some one of these other insects the following brief notices of the more important of these enemies 1 have abridg ed from the accounts comprised in dr t w.harris's " treatise on some ofthe lu st cts of new england which arc injurious to vegetation ;" camb lspj 159 pages 8vo a work of great interest and value in it the inquirer will find a faithful di gest of all the reliable information we have on thc numerous insects which in jure our plants fruits and trees ;
